Our bamboo interdental brushes provide a sustainable alternative to your traditional plastic brushes. The compostable handle is made of sustainably grown MOSO bamboo (not eaten by Panda). There are eight brushes in each pack. They help you access even the most hard-to-reach places between your teeth and gums delivering a more effective and deeper clean. The soft long-lasting bristles are made of coated wire and need to be removed before composting the handle. Our interdental brushes are designed for daily cleaning. They’re reusable and you don’t need to replace them after every use unless they're damaged or worn. * Small size: 0.6mm * Medium size: 0.
